Ugh, I had 5 broody's all raising chicks at the same time. With 3 of them being black Silkies it did get a little confusing to some of the chicks!
So far, I let only my selected breed rooster mingle with the flock and collect only eggs from the girls of that breed... making sure not to have hens with the same color eggs as my breeders. SFH are cream and FBCM are dark brown, with everyone else being somewhere in the middle. If any hens are too close to my breeder egg colors.. so far I have rehomed them. Other than that, I will definitely be using a tractor if I wanna hatch more than 1 breed at a time, which I think time wise and generationally may be necessary for my future purposes. Although hatching different colored eggs can create another challenge... I try not to overthink hatching and with a very dumbed down process still have decent results. I don't keep breeders with faults in my flock so I don't have to worry about hatching from them. If any stag got into my girl flock that isn't a selected breed, I make sure not to hatch any until well past the time of fertilization. I far prefer incubator hatching to broody cuz I don't like my girls sitting so long and losing condition. But LOVE adopting them babies. 2 girls are already broody again after raising 1 & 2 clutches already this year. But I'm up to my eyes in chicks for the season... maybe adopt more and smaller broods next year so I can spread out my mental chick capacity!
Emotionally by this time of the season every year I am totally burnt out from waking up at 5:30 (naturally) but not sleeping until 11 ish. It wears on my attitude (especially towards teen chickens harassing chicks and stealing food), I am noticing... So many things chicken are a learning process and figuring out what works for you as a person. 
My first duckling arrived yesterday! But we wanna hand raise them for friendliness since broody raised seem so much more cautious towards us. Broody raised is great but definitely not without its' own challenges and still requires plenty of work on my part. But my future goal would be all broody raised and I can't believe after seeing how many successful broody's I've had this year that it's a real possibility!
Raised chickens for 6 ish years now but this last year has been my first adventure into breeding, which has been both frustrating... and BEYOND rewarding! 
I think when I do separate breeders I may still have 5 ish hens. Being DP, gives me only 3-4 eggs per bird during my comfy hold time before setting/hatching. And ugh, even my breeders go broody... so may have that challenge of not enough eggs to collect as I go forward. But knowing this, I might plan my hatching around it. Still lots more to learn on my part!
Mine are on range all day long and when teaching babies, are some of THE BEST foragers. Standard pecking order issues take place and I'm OK with that as long as know one is being bullied. Remember, dynamite comes in small packages... and I've got a few hens with neck feathers missing from going rounds with the silkies. Don't mess with a broody mama. 
I would start making my plans.
